The test results need to find out the abnormal items. If all the items on a test are in the normal range, the test is not considered abnormal. If there are abnormal items, they will be elevated or decreased, and it will exceed the normal range of the test. If the normal range is exceeded, it will be marked with an upward or downward arrow, so that the specific abnormal test item can be known. By using the name of the test, you can search the Internet to understand its meaning. If you are not able to understand it yourself, it is recommended that you go to the hospital for further consultation.
